"The one thought that crossed my mind initially was, 'What if this doesn't work?' And I just had to push it out of my mind and keep going because I knew that's what I had to do," Snodgrass said.

With Snodgrass' help, the infant began breathing again. This story highlights the importance of learning CPR.

The American Heart Association, which has created CPR training kits for schools, says on its website, "Cardiac arrest is a leading cause of death in the U.S., but when ordinary people, not just doctors and EMS, know CPR, a victim's survival rate can double, or even triple."

Currently, twenty states, including Minnesota, Texas and North Carolina, require CPR training in order to graduate high school.

The family of the infant released a statement to ABC saying their daughter is happy and healthy. As for Snodgrass, she plans to join the National Guard when she graduates.
